Description
Verfahren zur Überführung von Flüssigkeiten oder breiigen Massen in trockne und gut. extrahierbare Forin Den Gegenstand des vorliegenden Patentes bildet ein Verfahren zur Gewinnung extrahierbarer Substanzen aus Massen, aus denen sich die Substanzen nicht oder nur unvollkommen abpressen oder durch sonstige mechanische Mittel entfernen lassen und die der unmittelbaren Extraktion, sei es durch Umhüllung der extrahierbaren Masse mit Fremdkörpern, sei es durch Emulsionsbildung u. dgl., Widerstand entgegensetzen.Process for transferring liquids or pasty masses into dry and good. extractable form The subject of the present patent forms a process for obtaining extractables from masses that make up the substances are not or only imperfectly pressed or by other mechanical means Let the agent be removed and that of the immediate extraction, be it by coating the extractable mass with foreign bodies, be it through emulsion formation and the like, Oppose resistance.
Insbesondere bezieht sich das Verfahren auf die Gewinnung extrahierbarer Substanzen aus solchen Massen, die auch dureh Trocknung nicht in einen extrahierbaren Zustand gebracht werfen können bzw. die nicht zur Trockne zu bringen sind.In particular, the method relates to obtaining extractables Substances from such masses that cannot be extracted even through drying Can be thrown in condition or which cannot be brought to dryness.
Der Erfinder hat nun gefunden, daß man derartige Massen sehr gut in eine extrahierbare Form bringen kann, wenn-man einerseits ihnen Stoffe zusetzt, die in den später anzuwendenden Extraktionsmitteln unlöslich sind, und anderseits das so vorbereitete Gut in an sich bekannter Weise durch @Zerstäuben in cinem trockenen warmen Luftstrom trocknet und es auf diese Weise in eine leicht extrahierbare Form bringt. The inventor has now found that such masses are very good can be brought into an extractable form if - on the one hand, substances are added to them, which are insoluble in the extractants to be used later, and on the other hand dry the material prepared in this way in a manner known per se by @spraying in cinem warm airflow dries it and that way in an easily extractable form brings.
Handelt es sich z. B. um die Gewinnung von Glycerien aus den Massen, die sich bei der Glyceringärung ergeben bzw. aus den Rückständen, die nach der Abscheidung der Hauptmengen Glycerin verbleiben, so zeigt es sich, daß diese Massen infolge ihres schleimigen Zustandes beim Trocknen Rückstünde ergeben, die sich nur schwer extrahieren lassen, und bei denen Idie zu extrahierenden Stoffe, z. B. durch Schleimstoffe, so umschlossen sind daß das Extraktionsmittel nur schwer zu den zu extrahierenden Substanzen-gelangen kann. Qibt man aber dem Extraktionsgut in diesem Falle beispielsweise Kochsalz zu und gewinnt den trocknen Rückstand durch Verstäubung und Trocknung. des Staubes, so erhält man ein Produkt, das mit Alkohol oder Äther leicht und vollständig zu extrahieren ist. In diesem Ealle wirkt das zugesetzte Salz nicht nur als Vefteilungssubstanz, um das Eindtringen des Extraktionsmittels zu erleichtern. Es führt vielmehr, sei es durch Verflüssigung,-sei es durch Coagulation, z. B. Schleim und Eiweißstoffe in eine Form über, in. der sie die Extraktion des trocknen Gutes nicht mehr behindern. Is it z. B. the extraction of glyceria from the masses, that result from glycerine fermentation or from the residues that arise after separation of the main quantities of glycerine remain, it turns out that these masses as a result Due to their slimy condition, residues result when drying, which are difficult to remove can be extracted, and in which the substances to be extracted, e.g. B. by mucilage, are so enclosed that the extractant is difficult to extract Substances can reach. In this case, however, the extraction material is given, for example Table salt is added and the dry residue is recovered by dusting and drying. of dust, a product is obtained which, with alcohol or ether, is easy and complete is to be extracted. In this Ealle the added salt not only acts as a distribution substance, to facilitate the penetration of the extractant. Rather, it leads, be it by liquefaction, -be it by coagulation, e.g. B. mucus and proteins into a form in which they no longer hinder the extraction of the dry material.
Man kann aber auch, wenn man z. B. mit Wasser extrahieren will, als Verteilungsstoff Kieselgur - oder ähnliches, wasserunlösliches Material verwenden. Der Zusatz von Verteilungsstoffen bei der Trocknung von Substanzen, auf deren Rückstände irgendein Extraktionsverfahren angewendiet werden soll, ist an sich besonders in der analytischen Chemie bekannt. Durch die Vereinigung dieses Verfahrens mit. der sogenannten Zerstäubungstrocknung ist aber ein technisches Verfahren geschaffen, das auch solche Massen, die in kompakter Form sich sehr schwer selbst nach dem Zusatz von Verteilungssubstanzen in extrahierbare Form bringen lassen, überaus günstig zu verarbeiten gestattet. But you can also, if you z. B. wants to extract with water than Use diatomite as a distribution material or similar, water-insoluble material. The addition of distribution materials in the drying of substances on their residues any extraction method to be used is particularly in itself known in analytical chemistry. By uniting this process with. the so-called atomization drying is a technical process created, that also such masses that in compact form become very difficult even after the addition of distributing substances into extractables Let shape, Permitted to process extremely cheaply.
